To all zo 7mm zl may concern.'

Be it known that I, Evnn'r KEPNER, a citizen of the United States,residin at Kokomo, in the county of Howard and tate of Indiana, haveinvented certain new and useful Improvements in Cotter-Pin-ExtractingTools; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in vtheart to which it appertains to make and use the same.

This invention relates generally to tools, but more particularly tocertain new and useful improvements in cotter pin extractingrtools.

he primary object of the invention is to provide a tool which isprovided with a device which will prevent the hook member which engagesthe cotter pin from becomingddisengaged from the same while being useAnother object of. the invention is to provide a device of thisclasswhich will be extremely simple, strong, durable and inexpensive inconstruction, one which will be efficient and reliable in operation, andwell adaptied to the purpose for which itis des1 e ith these and otherob'ects in view, the

invention consists of certain novel features of construction, and thecombination and arrangement of parts as will be hereinafter fullydescribed and claimed.

In ther accompanying drawings:

Figure 1 is a side elevation of a devlce constructed in accordance withthis invention, illustrating the manner in whichit is used'to extract acotter pin;

Fig. 2 is a similar view, partly in section of the device; and,

Fig. 3 is a transverse sectional view taken on the -plane indicated bythe line 3--3 of Fig. l.

Referring more particularly to the drawings, the numeral l designates ahandle which is preferably of wood and to which a cylindrical metal stem2 is connected at one of its ends in any suitable manner. The free endof the stem 2 is tapered and curved to form what may be termed a hook 3.Extending through the stem 2- and having its ends projecting outwardlyfrom opposite sides of the stem 2 is a pin- 4, the purpose of wlnch willbe hereinafter described. Slidably mounted upon the stem 2 is a' tube 5,the latter being provided with a longitudinally extending slot 6 whichreceives the ends of the pin 4 to prevent rotary movement of the tubewith respect to the stem and also to limit the sliding or longitudinalmovement of lthe tube upon the stem. The end of the tube 5 which isremote from the handle l is provided with a lip 7. This lip 7 is curvedlongitudinally and extends toward the hook 3 so that when the tube 5 isslid away from the handle 1 the lip will ride upon the adjacent side ofthe hook and over the point of the same. The other end of the tube 5 isprovided with an extension 8 having its free end upturned to form a lug9 which may be engaged when moving the tube upon the stem.

In using the device the tube 5 is first disposed adjacent the handle 1,and the hook 3 is inserted in the eye of the cotter pin to be removed.The tube 5 is then slid away from the handle 1 until the lip 7 isdisposed over and in contact with the point of the hook. This obviouslyprevents the cotter pin from becoming disengaged from the hook and byusing theouter portion or bend of the hook as a fulcrum in the' samemanner as a nail puller is used, the cotter pin may be easily removed.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and use of the invention will bereadily understood without a more extended explanation.

As various changes in form, proportion and in the minor details ofconstruction may be resorted to Without departing from the spirit ofthis invention, it is to be understood that l do not wish to belimitedto the construction herein shown and described other than as claimed.

I claim:

A device of the class described comprising a handle, a stem securedvatone end to said handle and having its other end tapered and curvedlongitudinally to form a hook adapted to be inserted into the eye of afastening element, a tube slidable rupon said stem and having alongitudinally extending slot therein, a pin secured to andprojectingfrom one side of said stem and extending through said slot to limit thesliding movement of said tube upon said stem and to prevent said'tubefrom retating with respect to In testimony whereof I have hereunto setthe latter, and a longitudinally curved lip my hand in thepresenee oftwo subscribing formed aft the end of said tube which is rewitnesses.
